Abstract
A method comprising heating by means of a heater a mixture containing combustible solids and water so as to convert at least potion of the water of the mixture to steam form and subsequently feeding the whole of the mixture to a combustion furnace or gasification furnace wherein the mixture is transported by means of a pump at least between the heater and the combustion furnace or gasification furnace, characterized in that the pump exhibits a discharge pressure of between 1.5 MPa over the intra-furnace pressure of combustion furnace or gasification furnace and 22.12 MPa, and that the mixture having at least potion of the water thereof converted to steam form has a flow rate of 6 to 50 m/sec in piping within the heater and piping from an outlet of the heater to an inlet of the combustion furnace or gasification furnace. In this method, at the feeding of the mixture containing combustible solids and water wherein at least potion of the water has been converted to steam form to the combustion furnace or gasification furnace, there is substantially no wear of the interior of the piping wherein the mixture flows and stable supply of the mixture to the combustion furnace or gasification furnace can be accomplished.
Claims (24)
1. A method for feeding a mixture comprising a burn able solid and water to a combustion furnace or gasification reactor, comprising heating the mixture with a heater to convert at least a part of the water in the mixture into a form of steam and feeding the whole mixture to a combustion furnace or gasification reactor, wherein the whole mixture is transferred between an inlet of the heater and the combustion furnace or gasification reactor by a pump, characterized in that a discharge pressure at the pump is higher than an inner pressure in the combustion furnace or gasification reactor at least by 1.5 MPa and not higher than 22.12 MPa, and that a flow rate or said mixture with at least a part of the water being in a foam of steam is from 6 to 50 m/s in a pipe in the heater and in a pipe between an outlet of the heater and an inlet of the combustion furnace or gasification reactor.
2. The method according to Claim 1, wherein a discharge pressure at the pump is higher than an inner pressure of the combustion furnace or gasification reactor by from 3.0 MPa to 15.0 MPa.
3. The method according to Claim 1, wherein a discharge pressure at the pump is higher than an inner pressure in the combustion furnace or gasification reactor by from 4.0 MPa to 15.0 MPa.
4. The method according to Claim 1, wherein said flow rate is from 8 to 40 m/s.
5. The method according to Claim 1, wherein said flow rate is from to 40 m/s.
6. The method according to Claim 1, wherein an inner diameter of the pipe in the heater becomes larger gradually along a direction of the flow of the mixture, so that the water in the mixture is gradually converted into a form of steam.
7. The method according to any one of Claims 1-5, wherein an inner diameter of the pipe in the heater becomes larger stepwise along a direction of the flow of the mixture, so that the water in the mixture is stepwise converted into a form of steam.
8. The method according to Claim 7, wherein a pressure reducing valve is provided between sections of the pipe with different diameters, so that the water in the mixture is converted into a form of steam with an aid of the pressure reducing valve.

16. The method according to any one of Claims 1-14, wherein the heating by the heater is carried out at a temperature of from 200 to 400 degrees C at a pressure of from 3.0 to 22.12 MPa.
17. The method according to any one of Claims 1-14, wherein the heating by the heater is carried out at a temperature of from 200 to 365 degrees C at a pressure of from 4.0 to 20.0 MPa.
18. The method according to any one of Claims 1-17, wherein the heating is carried out with a heating medium of a temperature of from 200 to 600 degrees C.
19. The method according to any one of Claims 1 -18, wherein a pressure control valve is provided between the outlet of the heater and the inlet of the combustion furnace or gasification reactor.
20 . The method according to any one of Claims 1-19, wherein a pre-heater is provided upstream of the heater.
21. The method according to Claim 20, wherein a pressure reducing valve is provided at the outlet of the pre-heater.
22. The method according to any one of Claims 1-21, wherein a water content in the mixture comprising a burnable solid and water is from 27 to 80 weight %, relative to the total weight of the mixture.
23. The method according to any one of Claims 1-21, wherein a water content in the mixture comprising a burnable solid and water is from 30 to 40 weight %, relative to the total weight of themixture.
24. The method according to any one of Claims 1-21, wherein a water content in the mixture comprising a burnable solid and water is from 30 to 35 weight %, relative to the total weight of the mixture.
